@daac double check your work to make sure everything is properly connected. Check the T-con board to ensure you changed like for like. The other thing you want to check is if this is a backlight issue. Once your TV is on and you have sound etc. shine a flashlight beam at an angle against the screen. see if you can make out shapes, silhouettes etc. If so, it is your backlight that does not come on. that could be an issue with the power board as well as failed backlight strips. Try this is a darkened room since it will be more visible.

Of course, you can always post some pictures of all of your boards with your Question. That allows us to see what you see and hopefully help you further.
